10. If TRS  SO converter efficiency is below 90% check for one of the
2
following possible causes:
Pneumatic leak
•
Perform a leak check (with the M501-TRS connected) as
•
described in the Detailed Pressure Leak Check section in the
T101 Manual - PN 07266.
Plugged or constricted pneumatic flow
•
• Perform a sample flow check as described in the Performing a
Sample Flow Check section in the T101 Manual - PN 07266. This
tests the entire system
Disconnect the gas feed line from the FROM ANALYZER port of
•
the M501-TRS. Attach the flow meter to the port and repeat the
test. Isolates the portions of the pneumatic system down stream
from the TRS  SO
in the flow test.
Attach the flow meter to the FROM CONVERTER port at the
•
back of the T102. Retest. This bypasses M501-TRS during the
flow test.
Improper Set point temperature
•
• Call Teledyne API's Technical Support for advice.
Incorrect/wrong concentration Span Gas used in efficiency
•
test
• Independently verify the concentration of the span gas.
Contaminants in the converter chamber, pneumatic lines
•
Sometimes contaminants such as tiny particles of scrubber
•
material from the M501-TRS' SO
converter tube and react with the TRS  SO
process. This can occur if the filter material inside the scrubber
lets any particulates through.
Call TAPI Technical Support for instructions on cleaning the
•
converter tube and M501-TRS pneumatic lines.
